RE: Megaco digitmap

Hi Ramesh,

 

I think [0-9EF].L means, any number (including zero digits) of digits (from 0 to 9, E = * and F = #) followed by a long digit time out. You could check out H.248.1 Annex E.6 DTMF Detection Package.

 

Regards,

Sriram

Thanks for the clarification.  So E is for '#' and F is for '*' ?  Is there a RFC that maps these?

 

Thanks once again.

To me this means that any of the digits 0-9, # and * are ‘expected’ and that the Long timer is applied after every digit is dialed.

 

My apologies if this interpretation is incorrect.

RE: Megaco digitmap

Check out the digitmap example in 7.1.14.9 of the V2 document.  Also, the DTMF generator/detection packages details.

RE: Megaco digitmap

Follow ITU-T H.248.1 Annex 4, 5 and 6 you can find the packets related with this mapping.

 

Signal name SignalID/Tone ID

DTMF character 0 d0 (0x0010)

DTMF character 1 d1 (0x0011)

DTMF character 2 d2 (0x0012)

DTMF character 3 d3 (0x0013)

DTMF character 4 d4 (0x0014)

DTMF character 5 d5 (0x0015)

DTMF character 6 d6 (0x0016)

DTMF character 7 d7 (0x0017)

DTMF character 8 d8 (0x0018)

DTMF character 9 d9 (0x0019)

DTMF character * ds (0x0020)

DTMF character # do (0x0021)

DTMF character A da (0x001a)

DTMF character B db (0x001b)

DTMF character C dc (0x001c)

DTMF character D dd (0x001d)

 

 

And these Signals ID that have a Tone ID related, is correlated with other table where you can translate these Tone ID in Digits:

 

DTMF Event Symbol

d0 "0"

d1 "1"

d2 "2"

d3 "3"

d4 "4"

d5 "5"

d6 "6"

d7 "7"

d8 "8"

d9 "9"

da "A" or "a"

db "B" or "b"

dc "C" or "c"

dd "D" or "d"

ds "E" or "e"

do "F" or "f"

 

 

So The Digit * is mapping to DS that is mapping to “E or e” and the Digit # to DO that is mapping to “F or f”.

 

Take care which event you are using in your Network, DD/CE or DD/STD, because each one can result in each table above.

 

Best Regards.

Distinguishing between Audio & Video Payload types using SR in RTCP packet

Hi

 

I recently started working in MG. I have a question regarding the sender reports in RTCP.

 

Can you tell me how can we distinguish between an audio & video payload type using the sender report data of an RTCP packet in ethereal?

 

Regards,

Ambesh

RE: Distinguishing between Audio & Video Payload types usingSR in RTCP packet

H.248 Interface:
Each RTP-based media component is mapped on a dedicated H.248 Stream.
Further: the RTP and RTCP flows could be both mapped on the same H.248 Stream. This is the assumption in all present H.248 profile specifications (with H.248 RTP terminations) as far as I know.
There are then two H.248 Streams, one for audio-over-RTP + RTCP and another Stream for video-over-RTP + RTCP.
 
=> Wireshark discrimination point: H.248 StreamID
RTP/RTCP-over-UDP/IP Interface:
Assumption: individual L4 ports for RTP and RTCP (i.e. the mode of Multiplexed RTP and RTCP on single L4 ports is not considered.)
=> Wireshark discrimination point: UDP port numbers
Of course, you've to correlate the info of both interfaces.
